Description

Bacti-Caps™ provide a firm, positive culture tube closure allowing a controlled gas interchange, thus proving a more practical alternative to cotton wool plugs. Suitable for all standard test tube sizes, they fit rimless and plastic tubes with an outside diameter of 13mm, 16mm, 19mm, 25mm and 38mm. The three flexible fins molded on the inner wall of each cap ensure a positive fit even when minor variations in tube size occur. Bacti-Caps™ are made from chemically resistant virgin plastic so they are unaffected by culture media, most acids, alkalis, alcohols and esters.
